Automatization of contact pressure measurement between trunk orthosis and patient's body using a matrix tactile sensor

Trunk orthosis affects trunk by a corrective-pressure mode with an objective to correct deformities (e.g. scoliosis). The effectiveness of this function depends on various factors, i.e. correct orthosis manufacture, correct application to patients and regular pressure corrective effect control. All these factors can be monitored by a system for measurement and evaluation of the contact pressure between the instrument and trunk in a real time and also by a so called “off line” system data recording. Presented article describes the application of made-to-measure sensor system TACTILUS (Sensor Products, USA) in different regimes (ambulance – A, home – H, combined – HA and multi-sensory ambulance – MA regime), testing of chosen static and dynamic matrix tactile sensor (MTS) parameters and results of the testing application between orthosis and patients' trunks.
